I just did a valve job and put headers on my '93 4runner with V6. I am not certain I got all the vacuum hoses on correctly. There is a good illustration in the factory repair manual for the vacuum hoses related to the EGR and PAIR valves so I think I have those right. But I can't find anything that clearly shows where to connect the vacuum hoses that go to the power steering and the two hoses that run to a valve mounted on the fender (not sure what this valve is).

I have posted a couple of pictures that show how I have connected the hoses at http://members.aol.com/isensee/4runner1.jpg and http://members.aol.com/isensee/4runner2.jpg. Does it look correct? If not, can anyone tell me what I need to change or point me to a picture that shows the correct hose connections?

 

Power steering hoses look correct.
